Deploy the glance helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Glance Helm chart on Kubernetes using Pulumi, we're going to use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This allows us to specify and deploy Helm charts in a Kubernetes cluster.

Here's a step-by-step process of what we'll do:

Set up the Kubernetes Provider: We'll ensure that Pulumi can communicate with your Kubernetes cluster.
Define the Helm Chart: We'll specify the Glance Helm chart, setting up any necessary parameters for its deployment within the Pulumi program.
Deploy the Helm Chart: We'll execute the Pulumi program which will, in turn, deploy the chart onto your Kubernetes cluster.

For the following code to work, make sure you have Pulumi installed and your Kubernetes cluster is accessible via kubectl.

Let's start by writing our TypeScript program.

import * as k8s from '@pulumi/kubernetes';

// We create a new Helm chart resource, which is Glance. Glance is an OpenStack service where we
// can store and retrieve disk and server images.
const glanceChart = new k8s.helm.v3.Chart("glance", {
    chart: "glance",
    // Replace `<your-repository>` with the name of the Helm repository where Glance is located.
    // If the Glance chart is in a public repository, add that repository's URL to the `repo`
    // attribute.
    repo: "<your-repository>",
    namespace: "openstack", // Specify the namespace where Glance should be installed
    // `values` provides the configuration for the chart.
    values: {
        // You will need to add the specific configuration values for your instance of Glance.
        // This typically includes configuration for persistent storage, access credentials,
        // networking settings etc. The following is a placeholder for these values.
        // Make sure to consult the Glance Helm chart documentation to fill these out correctly.
        service: {
            type: "ClusterIP",
            apiVersion: "v1",
        },
        // ... add other configuration values as needed
    },
});

// Finally, if you want to access the deployed resources programmatically, you can export their details.
export const glanceServiceName = glanceChart.getResourceProperty("v1/Service", "glance-api", "metadata").apply(m => m.name);

// To run this Pulumi program, save it in a file with a `.ts` extension, for example `deployGlance.ts`.
// Then, execute it using the Pulumi CLI commands:
//
// pulumi stack init dev          # Create a new stack for the project
// pulumi up                      # Preview and deploy changes
//
// After deploying your chart, remember to clean up resources you're no longer using:
//
// pulumi destroy                 # Destroy all resources
// pulumi stack rm dev            # Remove the stack

Here are a few things to note:

The chart parameter is set to "glance", which should match the name of the Glance chart in your Helm repository.
The repo parameter must be set to the URL of the Helm repository that contains the Glance chart. Replace <your-repository> with the actual repository name.
namespace specifies the Kubernetes namespace to which Glance will be deployed. We're using "openstack" as an example; you may need to adjust this according to your setup.
The values block passes configuration to the chart. The provided values are an outline – you need to fill this in based on the Glance chart's requirements and your specific configuration needs.

After you've written your Pulumi program, you can run it using the Pulumi CLI as indicated in the comments at the end of the script. This will deploy Glance onto your Kubernetes cluster. Remember to configure your kubectl to point to the correct cluster where you want to deploy Glance.
